Withdrawal reflex. The withdrawal reflex ( nociceptive flexion reflex or flexor withdrawal reflex) is a spinal reflex intended to protect the body from damaging stimuli. [1] The reflex rapidly coordinates the contractions of all the flexor muscles and the relaxations of the extensors in that limb causing sudden withdrawal from the potentially ...
The crossed extensor reflex or crossed extensor response or crossed extension reflex is a reflex in which the contralateral limb compensates for loss of support when the ipsilateral limb withdraws from painful stimulus in a withdrawal reflex. [1] During a withdrawal reflex, the flexors in the withdrawing limb contract and the extensors relax ...
An integrating center, the point at which the neurons that compose the gray matter of the spinal cord or brainstem synapse. Efferent nerve fibers carry motor nerve signals from the anterior horn to the muscles. Effector muscle innervated by the efferent nerve fiber carries out the response. A reflex arc, then, is the pathway followed by nerves ...
Primitive reflexes. Primitive reflexes are reflex actions originating in the central nervous system that are exhibited by normal infants, but not neurologically intact adults, in response to particular stimuli. These reflexes are suppressed by the development of the frontal lobes as a child transitions normally into child development. [1]
Agility’s Digit wasn’t the only humanoid holding court at Modex in Atlanta this week. On the opposite end of the Georgia World Congress Center, Reflex Robotics, a younger and smaller startup ...
The plantar reflex is a reflex elicited when the sole of the foot is stimulated with a blunt instrument. The reflex can take one of two forms. In healthy adults, the plantar reflex causes a downward response of the hallux ( flexion ). An upward response ( extension) of the hallux is known as the Babinski response or Babinski sign, named after ...

Reflex. In biology, a reflex, or reflex action, is an involuntary, unplanned sequence or action [1] and nearly instantaneous response to a stimulus. [2] [3] The simplest reflex is initiated by a stimulus, which activates an afferent nerve. The signal is then passed to a response neuron, which generates a response.
Biceps reflex. Biceps reflex is a deep tendon reflex (DTR) test (also known as a muscle-stretch reflex test) [1] that examines the function of the C5 reflex arc and the C6 reflex arc. [2] The test is performed by using a tendon hammer to quickly depress the biceps brachii tendon [3] as it passes through the cubital fossa.
Corneal reflex. Examination of corneal reflex is part of some neurological tests. The corneal reflex, also known as the blink reflex or eyelid reflex, [1] is an involuntary blinking of the eyelids elicited by stimulation of the cornea (such as by touching or by a foreign body), though it could result from any peripheral stimulus.
